Abstract

In order to attain a frequency spectrum efficiency by narrowing channel interval without inducing interference from adjacent channels, a signal level of a mobile unit which requests channel access is detected at a land site. The signal level thus detected is used to assign a channel to the incoming mobile unit such that the assigned channel is adjacent to a channel whose signal level is closest to the signal level of the assigned channel. Further, in order to meet magnitude changes of received signals, the magnitudes are checked so as to reassign currently allocated channels.
